After more than a decade in engineering and business—and running from a call to ministry he received in high school—Rob Mehner was hired as an associate by a local church to help with their exponential growth. While working in that church, he received his master of divinity degree from Asbury Theological Seminary and was ordained in the United Methodist Church. But it was the work of God through the Holy Spirit, after years of spiritual stagnation, that changed his life, empowered his call, and inspired the class that God has used to change many lives and from which this study is born. Rob and his wife, Kristy, have two adult children, Stefan and Casey. After twenty years of pastoral ministry in local churches, he is serving as a missionary in Guatemala.
